Using the upgraded GRAVITY+ instrument on ESO’s Very Large Telescope Interferometer (VLTI), astronomers have measured the ratio of carbon isotopes in...
New research from Rice University suggests sulfur keeps Mercury’s interior molten at lower temperatures, offering new clues to how the planet’s strange...
Using the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have characterized the atmosphere of TOI-5205b,...
Using the Immersion Grating Infrared Spectrometer (IGRINS) on the Gemini South telescope at the International Gemini Observatory, astronomers have directly...
A new analysis of isotopic signatures across planets and meteorite parent bodies suggests our home world formed entirely from inner solar system material,...
Kepler-51 is a young G-dwarf star hosting three super-puffs and one low-mass non-transiting exoplanet. Kepler-51d, the coolest transiting planet in this...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have for the first time identified hydrogen sulfide gas in the atmospheres of three gas-giant...
The Moon formed from a giant impact of the proto-Earth with the ancient protoplanet Theia. In a new study, a team of scientists from the United States,...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected doubly deuterated water (D2O), or ‘heavy water,’ in the protoplanetary...
The discovery of 1I/Oumuamua, 2I/Borisov and 3I/ATLAS showed that significant numbers of interstellar objects populate interstellar space. Their omnipresence...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected silicate clouds in the atmosphere of the exoplanet YSES-1c and a circumplanetary...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected water, carbon monoxide, and silicon monoxide in the dayside atmosphere of WASP-121b...
Described in a paper that appears today in the journal Nature Astronomy, the discovery means habitable exoplanets could have started forming much earlier...
WASP-132 is a unique multi-planet system in that both an inner rocky planet and the newly-discovered outer giant planet are in a system with a hot-Jupiter...
In 2003, Hubble provided evidence of a massive exoplanet around a very old star. Such stars possess only small amounts of heavier elements that are the...
The newly-discovered exoplanet orbits TOI-3261 (also known as TIC 358070912), an inactive main-sequence star located 300 parsecs (978.5 light-years) away...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have captured high-resolution images of eight protoplanetary disks in Sigma...
